Barry Sherman and his wife Honey were found dead in the basement of their Toronto mansion last month, but Canadian police are yet to solve the mystery.

The Sherman family lawyer says a claim by the police that there was no forced entry to the Shermans' house may have misled the public.

Private detectives are also investigating the deaths as the family seeks answers.

It is nearly a month since Canadian pharmaceutical billionaire Barry Sherman and his wife, Honey, were found dead in the basement of their $5.4 million (£4 million) Toronto mansion — but there are still no answers.

Specifically, he thinks a that police statement, which asserted that there were no signs of forced entry to the Shermans' mansion, may have misled the public.

"It's simply absurd," Greenspan said. "You have to know a lot more before that becomes meaningful and before that becomes public. Because the public may draw from that an inference that is just wrong and misleading."

Citing police sources, Canadian publications have posited the theory that the deaths may have been a murder-suicide, but this was strenuously denied by the family.

Greenspan said he had not been given any new information by the police. "We've not engaged in discussions about the ongoing investigation," he told The Globe and Mail.

The Toronto Police Service did not immediately respond to Business Insider's request for comment.

The Shermans were found dead on December 15 in their basement by a real estate agent, who was visiting to help sell the mansion.

Barry is the founder of Canadian pharmaceutical firm Apotex Inc and had an estimated net worth of $3.2 billion, according to Forbes. The couple were known for their philanthropy, giving tens of millions of dollars to hospitals, universities, and Jewish organisations.
